Yu Kai spread his wings and chased after him in anger, "Damn it, you actually dared to pick my peaches and snatch the mutant beads that I worked so hard to get!" His angry shouts echoed in the air, filled with endless anger.

The shadow moved incredibly fast, streaking across the sky like lightning. Despite Yu Kai's best efforts, he could only keep a distance to avoid being lost. After running for a long distance, the shadow finally stopped in a remote area. Yu Kai landed quietly, holding his breath and concentrating. He watched as the shadow cautiously scanned its surroundings, confirming it was not being followed, and then headed towards the dark and eerie woods. Just as Yu Kai was about to follow, another shadow flew over. This one, after also observing its surroundings, also plunged into the woods without hesitation.

Yu Kai cautiously followed them. As soon as he entered the woods, a strong chilling feeling washed over him, making him feel extremely uncomfortable. The two figures were like ghosts, leaving no footprints. Yu Kai circled the woods a few times before completely losing sight of them.

Unwilling to give up, Yu Kai's spiritual energy surged. It danced and flickered across his body, instantly covering his arms, abdomen, and back with a layer of solid metal armor. He used his spiritual energy to search carefully.

In the gloomy woods, invisible spiritual energy penetrated the layers of branches and leaves, leaving no corner untouched. Finally, as it swept across the ground, it discovered some subtle traces: the energy fluctuations left by the movement of two dark shadows. He took a deep breath and prepared to continue following these clues.

A mysterious tomb lay hidden underground. Yu Kai carefully explored the surroundings and finally discovered a narrow cavern that seemed to lead inside. He wondered if it had been left by tomb robbers. Standing in front of the cavern, Yu Kai felt a wave of unease, wondering what dangers lay beneath. However, thinking of the precious mutant pearl, his desire to find his mother as soon as possible, and his desire to rescue Sister Yuening and the others who had been captured, he gritted his teeth, his gaze grew resolute, and he finally leaped down.

After groping for a while, he carefully passed through the narrow and dark passage and finally arrived at the main tomb. He saw a mutant zombie dressed in ancient clothes sitting upright in a huge coffin, its face twisted and strange, emitting a chilling aura.

Two dark figures knelt on the ground, each holding two mutant beads. They lowered their heads deeply, their bodies trembling, demonstrating extreme reverence. A thick dark energy permeated the main tomb.

Yu Kai hid in the shadows, his heart beating rapidly. "This guy is so strong!" He tried hard to suppress his breathing and muttered in his heart: "Steal my mutation beads and give them to this old zombie! No, I must take them back!"

Seeing the mutant zombie fly out of the coffin, Yu Kai no longer hesitated. In an instant, he burst out with astonishing speed, suddenly stood up like lightning, and kicked it back into the coffin with a force of a thousand pounds. The kick was so powerful that it made the entire coffin tremble.

The two black shadows looked up instantly, but before they could react, Yu Kai had grabbed the four mutant beads at the same time like a ghost, and retreated in a flash.

Two dark figures roared in anger and launched their attacks, their fierce attacks bearing down on Yu Kai. Undeterred, Yu Kai sheathed his mutation bead and charged head-on. A mechanical arm flashed with blinding light, blasting towards the two with unparalleled force. With a resounding "bang!" like a thunderous explosion, the two were sent flying, slamming hard against the solid tomb wall. Vast cracks instantly appeared in the wall, sending rubble tumbling down.

"Roar!" The enraged mutant zombie flew out again. Seeing the mutation bead taken away, its eyes bloodshot, and its long, knife-sharp claws swiftly clawed at Yu Kai. Yu Kai reacted quickly, spun around, and engaged the zombie with exquisite agility. For a moment, the two sides exchanged blows, fists and claws crisscrossing, and the tomb was filled with powerful energy.

With a muffled "bang!", Yu Kai was flung back by the mutant zombie's powerful force, slamming heavily into the wall. Blood flowed from the corners of his mouth. Without hesitation, he immediately pulled out two mutant beads and swallowed them in one gulp. This action further incited the mutant zombie, which roared and lunged at him, swift as the wind. Yu Kai quickly dodged, and the zombie's hands pierced the solid tomb wall, sending gravel flying.

Yu Kai's injuries quickly healed under the power of the mutation bead, and his strength increased significantly. Brandishing his mechanical arm, he once again engaged the mutant zombies in battle. The two sides exchanged blows, each collision producing a deafening roar. With a loud "bang," Yu Kai was sent flying again, smashing the massive coffin in the center to pieces.

The mutant zombie leaped up, stomping down at him with overwhelming force. Yu Kai quickly rolled to the side, narrowly avoiding the impact. The zombie stabbed him with both hands, instantly creating two bottomless holes in the ground. In his haste, Yu Kai spotted the long sword hanging above the gate, and an idea struck him.

Yu Kai spread his wings, flew up, and snatched the longsword away. The mutant zombie flew over again, and Yu Kai didn't hesitate, stabbing it with his sword. The mutant zombie, feeling the threat of the longsword, dodged hastily.

Yu Kai seized the opportunity to pursue, his sword swift as the wind, its shadows heavy. Facing the long sword, the mutant zombie showed a clear fear, its movements becoming somewhat slow. Yu Kai swung his sword, piercing the mutant zombie's body with deep cuts that could be seen through the bone. As the zombie dodged, Yu Kai found the perfect moment and stabbed him between the eyebrows.

A miserable scream was heard, black smoke emanated from his body, and a bright mutant bead appeared, which Yu Kai immediately caught.

Seeing the two shadowy figures flee, Yu Kai drew his sword and gave chase. As Yu Kai emerged from the cave, a shadowy figure suddenly struck him over the head with a bone club, lightning fast. Yu Kai's mind raced, and his entire head was instantly covered by the mecha. With a thud, Yu Kai was finally knocked down, but he quickly stood up, his eyes blazing with anger.

Yu Kai madly poured spiritual energy into his body, and shot out with his longsword. The shadow tried to attack again, but Yu Kai was faster, grabbing his bone club with one hand and stabbing his longsword into his abdomen. The shadow roared, its body disintegrating into smoke and dust, dropping a mutant bead.

Yu Kai grabbed the mutation beads and, without stopping, continued his pursuit. The shadowy figure had been incredibly cunning, having robbed him of so many mutation beads, yet only surrendered two to the mutant zombie. Yu Kai was determined to catch him.

Yu Kai roared at the fleeing shadow, slashing with his sword with all his might. The immense force of the sword, accompanied by a sharp gleam of light, instantly sent the fleeing shadow flying. The shadow fell heavily to the ground, rolling several meters away, leaving a deep mark in the ground.

The black shadow saw Yu Kai flying down like a god descending from heaven, his eyes filled with fear, and he immediately knelt down and begged for mercy. At the same time, he took out several mutant beads tremblingly, raised his hands above his head, and his body kept shaking.
